# AudioRecord.MetricsConstants

`public static final class AudioRecord.MetricsConstants`
`extends Object` ``

java.lang.Object
↳ | android.media.AudioRecord.MetricsConstants

## Summary

### Constants
`String` | `CHANNELS` Key to extract the number of channels being recorded in this record track from the `AudioRecord#getMetrics` return value.
`String` | `ENCODING` Key to extract the audio data encoding for this track from the `AudioRecord#getMetrics` return value.
`String` | `LATENCY` This constant is deprecated. Not properly supported in the past.
`String` | `SAMPLERATE` Key to extract the sink sample rate for this record track in Hz from the `AudioRecord#getMetrics` return value.
`String` | `SOURCE` Key to extract the source type for this track from the `AudioRecord#getMetrics` return value.

### Inherited methods
From class `java.lang.Object`
`Object` | `clone()` Creates and returns a copy of this object.
`boolean` | `equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void` | `finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>` | `getClass()` Returns the runtime class of this `Object`.
`int` | `hashCode()` Returns a hash code value for the object.
`final void` | `notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void` | `notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String` | `toString()` Returns a string representation of the object.
`final void` | `wait(long timeout, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void` | `wait(long timeout)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void` | `wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.
